Abstract: A low loss fiber optic coupler is fabricated by forming a coupler preform (21) having a plurality of spaced glass cores (26, 27; 26', 27') extending longitudinally through a matrix of glass (21) having a refractive index lower than that of the cores. The coupler preform is heated and stretched by first pulling means (40, 76) to form a glass rod which is drawn by second pulling means (46, 77) past an intermittant source of localized heat (451. When the localized heat source is turned on, the second pulling means (46, 77) draws the rod downwardly at a rate faster than the first pulling means (40, 76). Since the rod is softened by the localized heat source, a necked-down coupling region (51) is formed. The rod is severed to form a plurality of coupler units (81, 87). When an end of a unit is immersed in acid, the matrix glass dissolves, thereby leaving the unit cores and surrounding etch-resistant cladding glass protruding from the newly formed endface of the unit.

Abstract: A temperature compensated sense amplifier is connected to the sense node of a memory array which is OR tied to the bit lines of the array. A PNP current mirror supplies voltage independent controlled current to the sense node. A level shifting stage is connected to the sense node to establish a threshold sensing level, and to switch on to steer the current into the amplifier stage. A compensation stage is connected to the level shifting stage and the amplifier stage to compensate for the β factors of the transistors and the resistive changes with temperature. A temperature compensated current sink is connected to the PNP current mirror to track over temperature in opposition therewith and maintain a constant current into the sense node. The level shifting stage and the amplifier stage also include temperature compensating features to provide a sensing threshold which tracks constantly over the operating temperature range.

Abstract: A sequential decoding device for decoding a data expressed by a systematic code having a symbol memory (22), a maximum likelihood path decision circuit (23), and a path memory (24), includes: an overflow detection circuit (25) for detecting an overflow of the symbol memory (23), and a switch (26) for supplying signal bit data, as an decoded output, read from the symbol memory (22) directly to the path memory (24) in correspondence with an overflow detection signal from the overflow detection circuit (25). The device includes further a path metric value increase/decrease monitoring circuit (24) for monitoring the increase/decrease of a path metric value delivered from the maximum likelihood path decision circuit (23) and controlling the switch (26) in such a manner that, when a monotonous increase of path metric value is detected, the decoded output of the maximum likelihood path decision circuit (23) is supplied to the path memory (24) instead of a direct supply of the decoded output of the symbol memory (22) to the path memory (24).

Abstract: Error signals from disk drive arm electronics on a transducer supporting actuator are decoded such that they require fewer communication lines than the number of potential error signals. A plurality of error detection circuits, each having an output indicative of an error condition or an error free condition are included in the arm electronics. An error decode circuit in the arm electronics receives outputs from the error detection circuits. The error decode circuit decodes the outputs from the error detection circuits to a decode output having less output lines than there are error detection circuit outputs. One set of conditions on the output lines of the decode circuit is representative of error free operation of the disk drive. The other sets of conditions on the output lines of the decode circuit are representative of error conditions.

Abstract: A fractional horsepower PMDC motor has a velocity indicating device positioned around the commutator (l2), between the brush gear (l3, l4) and the armature (8). The device comprises a conductor (l9) in the form of a square wave copper strip (30) which is printed on a flexible support (3l) and centred on a circle about the motor shaft (5), and a magnet assembly (2l) mounted on the armature (8). Magnet assembly (2l) comprises radially extending blades (25) which are formed from plastics bonded magnetic material. The blades (25) are magnetised so that adjacent blades have opposite polarity. As the magnet rotates with the shaft, the blades (25) move relative to the conductor (l9) and so induce an electrical signal in the conductor. The signal can be monitored to indicate the motor speed as is generally known. The blades (25) also act as a centrifugal fan, helping to cool the motor.

In this case, the current source 11 and the current pickups 18, 19 are in simultaneous, permanent connection with the drive motor. If the current supply apparatus 10 is separated from the mains current supply, the internal current source 11 automatically comes into operation and allows further driving operation until it has been discharged. The current conductors 7 on the link pieces 2 are formed either by metal foils or metal foil portions, by electrically conducting mouldings 7' which can be plugged in a clamping manner onto the individual link pieces 2 and can be plugged detachably either onto the edge parts 5 or in the region of the track surfaces 8 of the link pieces 2 or are fixedly and non-detachably connected to the link pieces. <IMAGE>

Abstract: The toner density control device of the inven­tion is adapted to an image forming apparatus in which a plurality of processes for image formation are exe­cuted, and includes a toner sensor (12) for detecting toner density in a developing section (6) of the image forming apparatus, toner supplying means for supplying toner to the developing section (6) according to out­put of the toner sensor (12), and cancelling means for temporarily cancelling function of the toner supplying means or output of the toner sensor (12) in response to switching of operations in the process for image formation. Even if a meachanical vibration is genera­ted during switching of operations in the process for image formation, the function of the toner supplying means or the output of the toner sensor is temporarily cancelled, so that an erroneous detection of toner density or inappropriate toner density oontrol based on the aforesaid errorneous detection can be avoided. Accordingly, it is possible to prevent such a drawback that the density of a formed image becomes too dark or too weak in places due to mechanical vibration in the process of the image formation.

Abstract: A data processing method for storing groups of related information in a storage subsystem of a data processing system in which the storage subsystem includes one or more storage devices having a plurality of block addressable storage locations (blocks or sectors) each of which stores a predetermined fixed number of bytes of said information. The method includes the step of establishing allocatable increments of storage, called physical partitions, which comprise a predetermined number of contiguous addressable blocks, and initially allocating, in response to a request to the operating system, a preselected number of partitions for each group of related information, where the partitions in each group are not necessarily physically contiguous and where the number that is selected is the minimum number of partitions required to store the group of related information. The method further includes the step of automatically allocating one or more additional partitions, located physically on any device, to a previously allocated group of related partitions, dynamically in response to another request of the operating system. A group of partitions that have been allocated to store a group of related information, such as individual files that are related in a hierarchical file system, is called a "Logical Volume". Logical Volumes may be further combined for administration and data management reasons into a "Volume Group".
